To all whom it may concern:

'Be it known that I, STACY B. I'lASEIJIINIG, a citizen of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented a certain new and useful Improvement in Draft-Yokes for Railway-Car Draft-Rigging. of which the 'iollowin is a full clear concise. and exact description, reference being. had to the accompanying' drawings, forming a partof this specification.

My invcntionrelates to draft yolies for railway car draft rigging.

The object of my invention is to provide a draft yoke in which a secure connection between the yoke and draw bar is afforded,

and in which the draw bar is readily removable from the yoke.

In the drawingsdorming a part of this specificati0I1---Figure 1 is a perspective view of a portion of a draw bar and of a draft yoke embodying my invention; Fig. 2 is a vertical longitudinal sectional view partly broken out; Fin. 3 is a detail of a portion of the detachable limb of the yoke; Fig. l is .a detail view showing the key in pcrspeo tlv'e view; Fig. 5 is a persj'iective view of the 14-, a lower detachable limb 15, and a connecting thimble 16. The upper limb 14: is forwardly;provided with a transverse inturned Q'll) 17 adapted to ei'lgage the shonlder 19/01 the draw bar, and is provided with the inwardly projecting lugs 18,-18 adapted to enter the rivet holes 10; 10 in the face of the draw bar adjacent thereto. The said upper lin.b 14 is provided with preferably integral downwardly extended lateral plates 19, 19 joined together at their bottom ends by the plate 90, and forming; with the upper limb the walls of a hollow head within which the draw bar is received. The

lower plate 20 is upwardly and rem-wardlv tapered on its inner face 21 to conform to the adjacent tapered :face of the key 23. '.he rear end of said upper limb 1-1- is provided with a llltlllSVOlSGllltilllllfl i l, which in preferable construction has an outward bend 25 therein, and is preferably with the rear end of the upper limb provided with the reinforcing flanges 2U. 2(5.

The detachable limb 15 is adapted at its "forward end to enter the hollow head here inbe'fore described, and is n'ovided with means to engage the lower face of the draw bar 9. At its forward end the detachable limb 1.5 is provided with a transverse in turned oil) 27. which is adapted to engage. against the shoulder 13 of the-draw bar, and isalso provideel on its innerface with the lugs -23, 28. which are adapted to enter the holes 10, 10 in, the adjacent face of the draw bar.

At a point substantially innrmdiately back of th rear edge 29 of the lower wall 30 forming the yoke head the detachable limb If) is provided with a depending liang'e Ill) having a perforation 3i therethrourrh for the passage of the bolt 32, which is received in the key 93 through the longitudinal perforation 33 thereinythc said bolt being pro-' vided at its rear end with a head i-l-l. and at its forward end is suitably threaded to receive the nut 'l heg ahldzcy 23 is adapted to enter the hollow head between the detachable limb and the lower wall 20 of said head, and by means of the said bolt '36 being substi'intially parallel and in the same plane with the forward face 40 of the upper portion'o'f the t'ansverse member 24 of the limb 1-1.

A perforation 41 in one of the il'ansres 36 registering with a. perforation -1l2 in the transverse member 24 of the limb 1. 1 is adapted to receive a bolt 43, which is provided at its rear end with a head 44'. and is suitably threaded. at its forward end to r ta -16, adapted to enter the opeir ends 47, if ofthe said thimble. The said lugs conform in shape to the openings in the ends of the thimble, and in preferable construction are integral with the limbs of the yoke.

To remove the draw bar from the yoke the bolt 32 is driven rearwardly out of'the key 23 and the flange 30 with which the detachable limb 15 is provided, and the key 23 removed from the hollow head. The bolt d3 is removed from the rear end of the yoke, whereupon the detachable limb is dropped within the head and at its rear end, dropping the draw bar and disengaging the upper shoulder 12 thereof from the gib 17, and disengaging the lugs 18 from the rivet holeslO, 10 in. the draw bar, where upon the draw bar may be disengaged from the detachable limb and removed forwardlyfrom the yoke. That the thimble l6 and draft rigging springs and followers may be removed upon the separation of the limbs of the yoke will be obvious.

in the modification illustrated in Figs. 7 and 8 the numeral 4:8 represents a draw bar, 49 the butt thereof, 50 the draft yoke comprising an upper limb 51, a lower limb 52 and a connecting thimble 53. The upper limb 51 is forwardly provided with a transverse inturned gib 5-1- adapted to engage one of the shoulders 55 of the draw bar, and is also provided at its forward end with depending plates 56, 56, forming with the lower plate 57 a hollow head 58 to receive the draw bar. The lower plate 57 is tapered on its inner face 59 to receive the taper key 60. which is employed to secure the detachable limb 52 within the head and in engage ment with the draw bar.

The upper limb 51 is provided with a downwardly extended flange 61 adapted to meet an upwardly extended flange 62 with which the lower limb 52 is provided, forming a wall at the rear face 63 of the coupler butt. The upper limb is also provided with a preferably integral downwardly extended thimble 64, preferably hollow at its lower end to receive the upwardly extending lug 65 with which the lower limb 52 is provided. At its rear end the upper limb 51 is provided with a transverse downwardly turned member 66, having in preferable construction the integral reinforcing flanges 67, 67 which extend downwardly beyond the lower end 68 of the said transverse member, forming between them a slot 69 within which the rear end of the lower detachablelimb 52 is received.

At its rear end the lower limb 52 of the yoke is provided with an upturned trans verse flange 70 adapted to engage the rear face 71'of the transverse member 66 of the upper limb of the yoke, the said lower limb 52 being, held in engagement with the upper limb at the rear end by means of the bolt 72 passing through the lower ends of the flangesbflyfi? and the preferably integral flanges 79, 79 provided at the rear of the detachable limb. The bolt 72 is thus in double shear. 1

At its forward end the detachable limb 52 is provided with an inturned gib 7? adapted to engage the adjacent shoulder 74: of the draw bar, and immediately back of the hollowhead of the upper limb is provided with a depending flange 75 adapted to engage the rear edge 76 of the member 57 of the hollow head, which said flange is provided with a perforation 77 to receive the bolt 78 which passes through the key 60, and is adapted to be employed in drawa ing the taper key 60 into position and Se curing the same within the hollow head,

To remove the draw bar the bolt 72 is removed, the bolt 78 withdrawn from the taper key 60, which may then be removed, dropping the detachable arm 52, whereupon the draw bar may be forwardly withdrawn from the yoke or the draft rigging dropped.
